Understanding the Basics of Percentage

A percentage is essentially a way of expressing a number as a fraction of 100. The word "percent" comes from the Latin "per centum," meaning "out of one hundred." So, when you say "X percent," you mean X out of every 100. This concept is vital in various calculations, from figuring out sale prices to understanding statistical data.

The Core Formula: Unveiled

The most basic formula to find percentage of any amount is:

Percentage = (Part / Whole) × 100

Where:

  • Part is the specific amount you're interested in.
  • Whole is the total amount or reference value.

For instance, to find what percentage 15 is of 200:

Percentage = (15 / 200) × 100 = 7.5%

Therefore, 15 is 7.5% of 200. But why perform this manually, when PercentageFinder.org can give you the answer instantly?

Percentage Increase and Decrease: Making Comparisons Simple

Percentages are also invaluable for comparing changes over time. To calculate percentage increase or decrease, use these formulas:

  • Percentage Increase = [(New Value - Old Value) / Old Value] × 100
  • Percentage Decrease = [(Old Value - New Value) / Old Value] × 100

For example, if your portfolio increased from $5,000 to $6,000, the percentage increase is [(6000 - 5000) / 5000] × 100 = 20%. PercentageFinder.org makes these calculations even quicker! You can also use percentage increase, percentage decrease calculators for quick calculations.
